One of most important of cybersecurity problem is a protection of infrastructure for external invasion.

This is also referred to some of public wireless networks. This wireless networks must be an public within selected area of space and provide the access, but for external users this networks must still be unavailable.

A lot of Wi-Fi networks in hotels, offices or cafe are still protected by “secret password”. This solution is not useful.


The combination of Wi-Fi transceiver and  NWG will be providing to estimate the range between access point and node. If the node is within serviced area then access will be granted, else the connection will be terminated. And no more “secret password” will be required.

This is also referred to password protected network, than this will be implement two-factor authentication (2FA or MFA).
